The studio

The engineering team you keep, not the agency you replace.

Curiosive is the software practice of Ugur Kellecioglu, working from Ankara / Türkiye with founders and product teams worldwide. Fifteen-plus products shipped across web, mobile, AI and browser extensions, from two-week prototypes to platforms serving a million users. Most clients start with one project and stay.

Partners, not vendors

Our work is measured in years, not deliverables. We stay through launch, the messy middle, and whatever the roadmap turns into next.

AI-native, engineer-led

AI drafts a large share of our code. What ships is decided by people who have run these systems in production and know how they fail.

Field experience, not prompt luck

We were shipping products years before the models arrived. That is the difference between code that generates and code you can operate.

Approach

AI is the future. In the right hands.

AI-written code has earned its reputation: quick to produce, expensive to own. Leaky permissions, silent data bugs, dependencies nobody vetted, a codebase that nobody on the team can safely change.

None of that is inherent to the tools. It is what happens when nobody in the room has operated the thing they are generating. We have been shipping production software for more than five years, most of it before a model could write a line of it, so we know exactly which parts deserve suspicion.

We are not slower than an AI-first shop. We are just still accountable when it is three in the morning and something breaks.

AI does the volume

Scaffolding, migrations, test coverage, refactors that touch hundreds of files. AI helps draft the work; delivery estimates depend on scope, review and validation.

Engineers own the boundaries

Data models, auth, permissions, payment paths and anything touching user data are designed and reviewed by a person who has run systems like yours in production.

Security is a gate, not a hope

Every change is read before it merges. Secrets handling, input validation, access control and dependency risk get checked on purpose, because we know how each one fails.

You get code you can keep

Typed, tested, documented and readable by whoever comes next. No lock-in to our tooling, no black boxes, no generated sprawl nobody can safely change.

Services

9 ways we get things shipped.

Most partnerships combine two or three of these, and the mix shifts as the product does. We scope to the outcome you need.

Full stack development

Web platforms taken end to end: architecture, interface, database, deploy. Drafted with AI, reviewed like it is going to production, because it is.

TypeScript
Next.js
NestJS
PostgreSQL

AI product development

Semantic search over embedded catalogs, realtime voice sessions, LLM workflows that hold up outside a demo.

OpenAI
Vector search
LiveKit

Browser extensions

Products that live inside somebody else's product: overlays, injected UI, one-click actions across Chrome, Safari and Firefox.

Chrome
Safari
Firefox

Mobile apps

Cross-platform apps shipped to both stores, sharing a codebase and a design language with the web product.

React Native
Expo
Firebase

Platform & edge

Workers at the edge, object storage, SQL at the edge, custom domains provisioned on demand. Infrastructure that stays boring.

Cloudflare Workers

Marketing sites & SEO

Fast, indexable front doors with programmatic pages, structured data, and a CMS the marketing team can actually use.
